Abstract (en)
[origin: US5224583A] A plastic conveyor belt, formed of plastic modules having rows of first and second projections extending in opposite directions, is adapted to optionally receive one or more rollers for reducing backline pressure on the belt. The rollers are positioned directly on the connecting rods which extend transversely through the belt, by occupying positions where projections in a row of projections would otherwise occur. A module having one or more of such openings or voids may be a part of a set of component modules, some having voids for receiving rollers and some not having such voids. A belt may be formed of mixtures of said modules, with or without any rollers on the belt. In one preferred embodiment the modules are for a radius type conveyor, with the second projections having elongated, slotted openings to allow the modules to angularly collapse together at curves.
